Uploading image gets deleted when being cut/pasted with surrounding content

[f1ames]

📝 Provide detailed reproduction steps (if any)

A specific case of #16967.

1. Set network throttling to 3G in the developers console. A real scenario would be user having a slow internet connection.
2. Add some content (few lines) in the editor.
3. Add/insert image (e.g. via upload).
4. While the image is still uploading:
   1. Select line before image + image + line after image.
   2. Cut.
   3. Paste

✔️ Expected result

Image is pasted correctly and upload continues.

❌ Actual result

Pasted image is broken.

On 40.0.0 (up to 43...) nothing is really pasted and error thrown:

ckeditorerror.js:90 Uncaught (in promise) CKEditorError: Cannot read properties of undefined (reading 'isFulfilled')

And on the latest one (44.0.0) it works as shown in the video above, no errors, empty image pasted.
